Rating: 4/5Good Trackball Mouse

Pros: Been using this trackball mouse for more then 2 years and it is still responsive and functions properly. I love trackball mice so much that I ONLY use trackball mice. Usually by 2 years I have to replace them because I ware them out. Scroll wheel is different but I don't hate it.

Cons: Does not have very many clicky button options.

Other Thoughts: The price is very fair for what you get with this one.

I really wish there were more options available for people who enjoy a nice stationary trackball mouse.

Rating: 4/5Enjoyable.

Pros: SCROLL RINGThe scroll ring is probably the best feature of this device. It's the only kind of wheel similar to an ipod wheel for desktop computers. It's great to be able to scroll continuously forever without stopping and instantly changing direction. I wish i could buy a standalone flat or similar "wheel" just to use by itself.

Being able to just move the ball around is great. Sometimes i wish the ball was larger but i don't have anything to really compare it with.

Cons: No middle mouse button. This is annoying but something you get used to eventually. I wish it had a middle mouse button or at least some additional buttons, such as back/forward.

The left click button began malfunctioning less than 2 years after use. It began misclicking, clicking multiple times, and "letting go" while holding the mouse unless pushing the button in a certain way. I wanted to send it in for warranty but I couldn't remember where I purchase it from to get a receipt. I was going to purchase a new one but instead, after much frustration, opened it up myself and opened up the left click switch which had a small flat metal "spring" with corrosion on the bottom. I cleaned the corrosion off with a mild abrasive (baking soda) and water and re-assembled and everything works great now. Other than dealing with the issue for so long, the actual repair was probably easier than any kind of warranty or RMA, though I probably would have used the warranty a year ago if i had found my receipt etc.

Dust and gunk will build up inside the ball "pit". It requires cleaning every so often, but isn't a huge deal to just pop the ball out and wipe off the light lens and ball. Sometimes the ball can get "stuck" when trying to do fine movements causing the mouse to not move or jump. Usually popping it out and back in is enough to fix any issue.

Rating: 2/5have chronic lateral epicondylitis? AVOID!

Cons: -THIS MOUSE IS WAY TO BIG to hold comfortably in your hands.-Buttons are very stiff compared to other mice.

Other Thoughts: I have chronic lateral epicondylitis. I must periodically cradle/hold the mouse in close to my body to avoid inflaming my arms. The Logitech Trackman (N82E16826104249) is a nice size for holding in your hands. THIS MOUSE IS WAY TO BIG to hold comfortably in your hands. After a decade of using many Trackman mice wishing it had a scroll wheel, I give this mouse a try. FAIL! This wide bulky beast can only be used on a desktop. I thought one of the main reasons for having a trackball mouse was so you could sit back and hold it without needing a desktop regardless of arm problems.....who wants to be quarantined to a desktop once you experience the freedom of a trackball?

Would be great if the buttons required normal compression and it was able to be hand held.

Cons: the scroll wheel feels cheap and loose. Also, it is a "smooth" scroll, no defined "clicks" like on most mice. Some people will enjoy this, I don't. The scroll ring, while a terrific idea and extremely useful, is the only thing to detract from the overall quality of the device. It just not at the same level of quality feel as the rest of the device

I wish the whole thing had more heft to it.

Other Thoughts: I wish there was a "middle click" button. I use that frequently to open links in new tabs or close tabs (#FirstWorldProblems). But I knew that going in.

Otherwise, this is great. If you want a high quality ambidextrous trackball at a great price, this is it.

Rating: 4/5Smooth Mouse

Pros: Great mouse and highly durable. Trackball on top is much more comfortable (For lefties and righties) and easier than it being on the side. Will take getting used to!! I find it to be more precise than regular mice. I will be 100% honest, this product is not for everybody. If you're serious about a trackball mouse, try something like this one first before dropping the big bucks on the multi button programmable trackball mice

Cons: USB cord could be a bit longer, but your standard extender can fix that. Why I left at 4 stars instead of 3

Other Thoughts: Great product, but like I said in the pro's this product is not for everyone, and it will take getting used to

Rating: 5/5First time trackball user

Pros: scroll wheel works fine, track ball is a good size. As a first time trackball user I was expecting awkwardness, and it was. Over time that has gone away. I was hoping it would be responsive and accurate enough for RTS games, it has been.

Rating: 5/5Made me a fan of trackball mice

Pros: Just set up my 2009 MBP with a 24inch monitor on my desk and needed a mouse and keyboard to finish the setup. I bought a standard laser mouse but since I was used to a trackpad, I felt like there was a lot of wasted movement. The scroll wheel is much more intuitive and effective that I had thought. Very stable while on desk. Even though this only has 2 buttons (3 using trackball works), I prefer it to the multi-gesture trackpad.

In brief: accurate, effective, and intuitive.

Cons: Only has 2 buttons, although using trackball works software adds one more button (simultaneous L/R button click) which adds mission control for mac.

Other Thoughts: Just set up my 2009 MBP with a 24inch monitor on my desk and needed a mouse and keyboard to finish the setup. I bought a standard laser mouse but since I was used to a trackpad, felt like there was a lot of wasted movement. Decided to
